Estimating the term…
A male fertility-inhibiting composition in unit dosage form, contains as an active ingredient a 6-chlorodeoxy-saccharide containing a pyranose or furanose ring of the formula ##STR1## where A represents the remainder of the pyranose or furanose ring, and has the formula C.sub.4 H.sub.7 O.sub.4 X (where X represents a hydrogen atom or another pyranose or furanose ring) in association with a physiologically acceptable carrier or excipient. The saccharide preferably contains a pyranose ring or furanose ring of the formula ##STR2## Also a method of controlling fertility in men or male animals comprises administering thereto a 6-chlorodeoxy-saccharide as defined above.
A male fertility-inhibiting composition in unit dosage form, comprising a unit dosage amount of, as active ingredient, a 6-chlorodeoxy-mono-or-di-saccharide of the formula ##STR6## where A represents the remainder of a ring selected from the group consisting of a pyranose ring or a furanose ring, and has the formula C.sub.4 H.sub.7 O.sub.3.OX (where OX is a substituent at the anomeric center and X is selected from the group consisting of a hydrogen atom and an aglycone, said aglycone being selected from the group consisting of pyranose, furanose and the 6'-chlorodeoxy derivative thereof) in association with a physiologically acceptable carrier or excipient.
A method of controlling fertility in men or male animals, in which a 6-chlorodeoxymono-or-di-saccharide of the formula ##STR9## where A represents the remainder of a ring selected from the group consisting of a pyranose ring and a furanose ring, and has the formula C.sub.4 H.sub.7 O.sub.3.OX (where OX is a substituent at the anomeric center and X is selected from the group consisting of a hydrogen atom and an aglycone, said aglycone being selected from the group consisting of pyranose, furanose and the 6'-chlorodeoxy derivative thereof, is administered thereto in an amount effective to control fertility.
